Abstract
A representation of a prosthesis opening is created and a device having a marker is tracked through the opening while monitoring the relative positions of the opening representation and the marker on a display. In one alternative, a representation is made on a display of the center of the contralateral stump opening and an electromagnetic marker coil that is secured to an endovascular delivery device, and the marker and delivery device are guided into the opening, while monitoring the relative positions of the opening center and the electromagnetic marker coil representations. In another alternative, one or more markers are positioned in the vicinity of the prosthesis opening and a device having a marker is tracked to the one or more markers and through the opening where the device is one of a guidewire and a catheter, while monitoring the relative position of the markers on a display.
